To all whom it may concern: A l

Be it known that I, WILLIAM'E. Srxsrrmno, of it. Joseph, in the countyof Buchanam'and State of Missouri, have invented certain'new and usefulImprovementsv in Hayand Cotton-Presses; and I do hereby declare thefollowing to be a fulliclear,` and exact description thereof, referencebein`ghad to the Accompanying drawings of the same, making partof thisspeciication, and in which- Figure lrepreseuts a side elevation; of afpress, embracingmy improvements;

Figure 2 represents a vertical section oil ythe same; Figure 3represents a horizontal section of one side af the press; and i Figure 4represents one of the gauge-slides, showing the scales by which themovements o ,theslides are graduated, and the scales for dete ming theweight oi' the bale. My improvements relate to that class o f;prcs'sesoperated by hand, and consist inconneqtji gthe. .fo1-

lower to the operating-screws, by means of 'haiiis and intermediatenuts, in connection 'with'auxiliarynts,' ner. .that

in either end of the followerin suoli a apap the power of the screw willbe applied to thez'ioilhwcr by means oi' chains and intermediate nutsonly at the commencement of the pressing, and subsequently through thedirect connection of the lfoll x\ vex 'by means of the auxiliary nutswith the screws, thereby obtaining a double connection with saidscrewsfor the purpose of 'increasing the power in proportion to theincreased resistance of the article being pressed, thereby relieving thescrews of the danger of breaking their threads, to which they arc alwaysliable with a single connection with the follower.

My improvement also relates to the arrawfement of gauging-slides,supported and operated by tht'cllower. for the purpose of ibrming thesides of theease, and regulating, during the operation of pressing, theposition of the follower, keeping it equal-at bhth ends, and. therebyprevent the binding ofthe fp lower-by reason of its assuming an inclinedposition v within the press, while heilig raised or lowered. l;

My improvement also consists in providing the-'slides with scales ofnumerals, arranged in connection ,with the 4scale of inches,for thepprposc oi'mcertalning and determining the weight of the bale, x 'rdiugto the degree of impression given to it bylf he press, whereby the pressis made to indica-te, arri-,oni tically, the exact weight of the balewhile linden".preislnc1 In the accompanying drawingss .7

The flame A ism-ade in the form oi' an iprightoblong box, supported b vsills B, and constructed 4in a substantial manner. Within this box,tlieffollower C is placed, and at thc top, thc head-block; Ltshingcd andsecured by rings E, fitting over the projecting ends F, of theheadblock, in the usual manner. The press is alsoprovided withside-doors G, hinged so as to drop down out of the way while strappingthe bale, and secured, when closed, by cross-bars H, fitting intostaples on the doors and the flame, in the usual manner.

At the opposite sides of the press, l arrange a vertical screw-shaft, I,permanently connected to the upper part of the flame, and supported by acollar, J. These screw-shafts I, do not extend to the bottom of theframe, but Aare united to the follower on either'side, by lmeans of twochains, L L, and an intermediate nut, M, so that when the follower isdown, it issuspended and supported by the chains alone, as shownintig. 1. The opposite ends of the follower project through openings N,in the sides of the box, and the chains L L, by whichthe follower issuspended, are placed on either side of, and parallel to thescrew-shaft, and'unite the followerto the intermediate nut M, which isprevented fromtuming with the'screw I by. contact with the side of theslides Q.

This connection of thc followerl with the screw, by means of the chains,is sutlicient to produce the vrcquired degree of power at thecommencement ofthe operation of compressing a bale, but as the pressingadvances, and the resistance of the bale increases, the strain upon thechains and the single connection ofthe intermediate nut` becomes verygreat, and endangers the breaking of the chains and the threads of thesaid nut. To prevent this, therefore, and to increase the power'of thescrew in proportion to the increased resistance of the bale, I arrangean auxiliary nut, P, in each end of the follower, fitted with a femalescrew of a. diameter corresponding to that of the screw-shaft, so thatthe follower ascends by its connection with the -intermediate nut, untilthe force upon the screws is measurably increased, when they are causedto take into the auxiliary nuts of the follower, as shown in iig. 2.Thus, 'the lower nuts come to therc'lif of the upper ones, andconstitute a double connection with the screw, thereby doubling thepower of the screw, by equaliziug the force between the intermediate andauxiliary nuts. This method of increasing the power of the screw is ofgreat importance, and permits the bale to'bc compressed with a' fargreater degree of compactness than could be obtained by the single con`n ection of the followerwith the screw, as heretofore.

In hand-presses, where the follower is operated by screw-shafts, theformer is liable to assume arr inclined position, and bind against thesides of the b'ox. To maintain the follower always parallel to the topof the press, I arrange a vertical-sliding gauge-board, Q,.on eitherside of the press, next to the screw-shafts, so

. are fitted into grooves a, fig. 3, in` the sides of thei turn theshaft, either to the right or left, to elevate or 'saving niucluy time,labor, and expense, in weighing the article after it is. pressed andbaled, it being ready thattheir lower 4endsrest upon the opposite endsof the follower," at V, fig. 2. These gauge-boards are of a lengthnearly equal to the height of the press, and

press, so as to close the opening N, in which the ends of the Iillcvfermove, and forma part of' the inner casing the Lbpposite sides of thepress, in such manner as t' 4rise and fall with the follower. Theseslides are prorlided with scales on their outer sides, so that theopblrators can observe, lalike from the opposite sidesinfl theV press,theexact degree of elevation or descent` `the slides, while .turning thescrews, and ther-ebl aintain the follower in a horizontal position, andeffect a free and perfect operation ofthe press.

The 'screws are provided, near their upper ends, with notched circularheads and `a. hand-lever, S, is also fitted tn eaclx ,screw-shaft, so asto ,embrace these notched; lxjea'da jin such manner that a' continuousspring-arm, T, secured to either side of thelever, will take iinto thenotches of the circular head, and Athus depress the follower. A

Both sides' of the gauge-boards may be provided with scales, so thateither operator-can see the scale of the opposite `gauge,.witl1outrequiring the operators to gtell the divisions of the scales as theoperation progresses, by which means they can always graduate theposition of' the slides.

vlhese' gauging-scales also perform :mother impor. tant fanctioxgthatofdetermining the exact weight of the bagby suitable figures, indicatingdifferent weights at diisent degrees of compression. This feature addsgreatlyto the utility of the gauging-slides, and constitutes n,automatic weighing-press, according to the degree'of.- compression thebale may receive, thereby forth,I rnarltet as delivered from the press.The gaugipg'mf' :the scales, to ascertain the weight, must be determinedfrom the area of the press, according to they degree of compression ofthe bale, indicated by. 'the ,sca-le.

- AsI'OttQn, hay, and hops, would occupy a different area, ithe'isamedegree of compression, there will be no difficult-yin determining theexact weight from the l BEST AVAlLABLE CQP subdivisions of the scales,and these several scalesI of' inches and numerals may be arranged to beread from the bottom or top ofthe slides, as convenience and facilitymay determine.

The scale of inches and feet is arranged 'so as to be read in connectionwith the scales of pounds and hun- Adred weight. The slides, therefore,serve three purposes, viz, movable slides to the openings Nain thepress-easing; to maintain the follower in a horizontal position; and toindicate., automatically, the weight ot the bale, when pressed, whateverthe degree of compression, or the character ofthe article being pressed.

The top of the fra me A constitutes the fixed guide, from which to readthe scales, and to determine'the position of the follower.

Having described my impmvements,

I claim- 1. The combination and arrangement of the intermediate nuts M,the screw-shaft I; and the connectl ing-chains L, with the follower O,and auxiliary nuts P, substantially as before described.

2. Thecombination and arrangement of the gang ing-slides Q with thefollower of a press, for the `pu!-- pose of ascertaining andregulating-the ascent and descent ofthe follower alike at both ends,substantially as before described. Y

3. The gauging-slides Q, arranged so as to-form the sides of' theopening N, in which the follower moves, while, at the same time, theyare free to rise and fall with the follower, as before described.-

4. The means herein described and represented for#l determining,automatically, in a press, the weight of the bale, according to itsdegree of' compression, substantially as before described.

5., The gauging-boards Q, provided with sea-les, for determining bothtbe degree of compression and the weight of the bale, according to anydegree of' compression, as herein described.

In testimony whereof, I have hereunto signed my name. L
